Abstract: According to one aspect of the invention, there is provided a waste collection system for separating liquid waste from solid waste which includes a conveyor having an upper conveyor roller, a lower conveyor roller and an endless conveyor belt extending around the conveyor rollers. The upper run of the conveyor belt is upwardly concave. In cross section, the upper run has a lowermost portion and lateral portions diverging laterally and upwardly from the lowermost portion. The upper run is longitudinally inclined from the upper roller to the lower roller. A waste deflector extends above and along the lowermost portion of the upper run. Separate liquid and solid waste collectors are located in the vicinity of the upper and lower rollers. A conveyor drive is connected to on of the conveyor rollers.

Abstract: A process for producing hot combustible gas free of sulfur, halogens and particulate matter. The process comprises passing oxygen, steam and/or carbon dioxide through a reaction zone containing an alkali or alkaline earth metal oxide, hydroxide, bicarbonate or carbonate and a carbonaceous fuel such as coal. The sulfur and halogen in the carbonaceous fuel are removed resulting in a combustible gas substantially free of sulfur, halogens and particulate matter.
